## What this tool does
Face-landmark AI: cutout, spec sizing and background swap — the professional grade.

## Typical user problems
- Strict validators check head position within a few percent. The Pro version detects facial landmarks and places your head to the exact spec — the compliance-grade option.
- When the application system validates face geometry (ICAO checks), heuristic alignment is not enough. This Pro version uses face-landmark detection for spec-exact positioning.
